SPECIFICATION forming part of Letters Patent No. 243,527, dated June 28, 18,81*,

Application filed February k17, 1R81.. (Model.)

To all whom may concern:

Be it known that I, CALVIN DILKs, of Allo- A waystown, in the county ot' Salem and State of New Jersey, have invented anew and Improved Vater-Wheel; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 isa vertical section through the penstock or case, showing the side of the wheel. Fig.`2 is a top view with a portion ot' the penstock and wheel broken away and shown in horizontal section. Fig. 3 is a detail, showing the shape of the bucket as cut out from plate metal.

My invention relates to an improvement in horizontal water-wheels of that form in which the water is admitted to the periphery of the wheel through lateral guides or chutes, and after striking the wheel is discharged there' from centrally, downwardly, and upwardly.

My improvement consists in the peculiar construction and arrangement of the buckets in the wheel, and in the peculiar arrangement of the wheel in the case for permitting its easy removal, as will be hereinafter more fully described.

In the drawings, A represents the penstock, between whose upper and lower walls is arran ged a circular series of water-guides, B. `The slots a and set-screws b, so that by extending them toward the wheel a smaller dischargeopening is left, through which the water passes, and consequently a smaller amount is deliv ered to the wheel.

Within the series oi' water-guides in the penstock is arranged the wheel, the lowerend of whose shaft yis stepped in a bearing in the bridgepiece D, beneath the penstock, while a bearing` in a second bridge-piece, E, above the peustock holds it steady. The wheel is composed ot a main hub'portion, F, which is rigidly fastened to the wheel-shaft by bolts, keys, or set-screws, and two rims or wheels, GG, connected to the 'hub by radial arms, which rims and hub may be cast in one piece. These rims have a wide peripheral portion, and to them are applied the buckets H, ot' a peculiar form. These buckets are made of heavy boiler-iron, with a rectangular portion, c, upper and lower wings, d d', and iiange e. The part c fits between the edges of the two rims, and, curving inwardly, constitutes the central discharge. wise upon the peripheral portion of the rims, the one above and the other below the waterguides, and are curved rearwardly, forming the upper and lower discharge. 'lhese upper and lower wings, d d', are provided on their edges next to the rims withears orl'ugsf, which areperforated and receive the two screw-bolts g that are employed for fastening in each bucket. The middle part of the bucket, or the portion in the line ot' the wings d d', is arranged on the The wings d d rest edge-v wheel very nearly radial to the center, while the Viiange c is bent forward in the direction of the movement of the wheel. The merit of this peculiar construction of wheel is that while the wheel discharges centrally, downwardly, and upwardly, the entrance of the edges of the two rims into the angle between the wings and rectangular portion c serves to separate the central discharge from the upper and lower discharge and holds the water to its proper place on the wheel. It also serves to brace and strengthen the connection of the buckets to the wheel, permitting them to be tirmly and detachably held in place by two screw-bolts. The lan ge e, on the exterior edge of thebucket, also secures an advantage, in that it gives an increased leverage on the wheel, and acts also to prevent the wheel from speeding when the work is off by producing a back action after a certain speed has been obtained.

To permit the wheel to be readily taken out, apair of detachable, semicircular, segmental rings, I I, are fitted at the upper edge of the IOO wings d. Between the abutting ends ot' these rings are forced wedges h 7L', which firmly hold the rings in place. By removing these rings it will be seen that the entire wheel may be lifted out.

The wheel, it will be seen, is perfectly symmetrical at its upper and lower edges, and this Y. enables it to be taken out and its position re- 1. The wheel composed of upper and lower rims, G G, and a hub, combined with buckets having the rectangular portion c and wings d d', the rims being tted into the angle between the parts c and d d, as described.

2. The wheel composed of upper and lower rims, G G, and a hub, combined with buckets having the rectangular portion c, wings l d', and ange e, arranged substantially as described.

3. The combination, with a wheel having the upper wings, d, andthe flanges e, of a penstock and detachable segmental rings lling the space between the inner edges of the penstock, the ends of anges e, and the outer edges of the wings d, to permit the wheel to be removed, as described.
